GRAIN-CONVEYER.

SPECIFICATION forming pm of Letters Patent No. 286,764, dated october1e, 1883.

Application filed August 2S, 1283. (No model.)

To all 1,071,011?, t may concern: I

Be it known that I, FRANK BIERCE, of Chicago, in the county of Cook andState of Illinois, have invented certain new and usefulV Improvements inGrain Conveyers or Transferrers; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the artto which it appertains tomake and use the same, reference being .had to the accompanyingdrawings, and to the letters of be -ioaded My present invention relatesto anovel construction of the transfer-car employed in this operation,whereby a more speedy action vis insured, space and material economized,and a more satisfactory and eflicacious result realized. Y

rIhe advantages of my invention are hereinafter set forth in detail, andthe particular features of novelty pointed out in the claims.

In the drawings, Figure 1, Sheet l, represents a perspective view of myimproved car, a portion being broken away to` show the internaldisposition of parts. Fig. 2, Sheet l, represents a similar `view of amodied form of the same, and shows the position of the weighing device.Fig. 3, Sheet 2, is a crosssectional view of the'two box-cars onseparate tracks with an intermediate transfer-car containing myimprovements. Fig/1, Sheet 3, is a like view, showing modications in theconstruction of the transfer-car. Fig. 5 is an end view of thetransfer-car, and Fig. 6 a crosssection showing a modification. Figs. 7.and

8 are detail views of the grain-elevator. Fig. 9 shows another means oftransferring grain, in which the grain is first elevated from the car tobe emptied intoabin or receptacle,then

weighed, and again elevatedto be elnptied into a removable spout ortrough, from which it is conveyed to the car or vessel to be loaded.

The body of the transfer-car is constructed in the main like that of theordinary box freight-car, which it exceeds in height to a greater orless extent, dependent upon the size and arrangement of the elevatingdevices within. Preferably near the end of the car is situated asubjacent box, A, extending as near the track as safety will permit.This box contains the elevator-housing, and directly above it the car isprovided with a gate, vBfor the admission of the delivery-chute C fromthe car to be unloaded. The gate, box, and elevator may, if desired, besituated at some other point in the length of the transfer-car, asillustrated in Fig. 2. Ihe steamimotor D, for operating lthe elevator,is situated at the end of the car, as shown. A belt from the fly-wheelof the motor drives the upper line of shafting,which imparts motion toelevator, to which the wheel F is attached. At the lower end of theelevator is placedthe idler G, supported in suitable bearings. Bothwheels are provided with projecting blades or sprockets H, which are sospaced as to bear successively during their revolution upon the uppersurface of the disks or blocks I, fixed upon the rope or chain K. Aseries of these wheels and idlers is mounted upon the upper and lowershafts, respectively,'each being Vfurnished with a separate rope andelevating disks or blocks, and having a common feed. Notable advantagesaccrue from the use of this series. upon the working parts is moreevenly dis tributed, the breakage of one of the ropes does not interferewith the continued operation of the` others, and the upperreceiving-spout, M,

in the forni of a chute.

The strain IOO To the bottom of the bin is attached a rope, l?,depending from an overhead pulley, Q, and operated by a winch, B, asshown in Fig. 4, or by other suitable means.

To the side of the car is attached the runway XV, by which the bin O isguided upon being elevated, assuming at different points the positionsshown in dotted lines in the drawings. The hinged roof-secti on S isdrawn up out of the way of the bin in its last position, where itdischarges its contents by means of chute T into the car X. The weighingdevice L, preferably a Fairbanks scale, may be placed beneath the bin,as illustrated in Fig. 2.

In Fig. l the bin O is provided with an inclined bottom, resting uponstrong frame-work for support. The lower left-hand side of the bin isprovided with a gate, Z, which is opened to discharge the contents whenthe bin is elevated. The roof-piece S is pivoted, before remarked, so asto swing out of the track of the rising bin. In the form shown in Fig.(i the bin is of such a form as to accommodate itself very nearly to theshape of the roof when discharging its contents.

The discharge-valve is provided with asprin catch, V, which isautomatically tripped by a projecting pin when the bin has reached itsupper position. The three modications shown, while differing in detail,have these generic features in common: first, they are verticallyadjustable in the car, so that after being completely filled they may beraised and discharged at once; secondly, they rest, while being filled,upon the bottom of the car, from which circumstance the height of theelevator, and consequently of the caritself, is materially lessened;thirdly, the walls or roof of the car are hinged, so as to permit theupwardly-moving and adjustable bin to assume the best possible positionfor discharging its contents.

A represents the car from which (in Fig. 9) the'grain or material is tobe taken, and A2 the car which it is desired to load.

CL is the transfer apparatus,provided at one side, within, with elevatorB2.

Cl is a chute extending from the top of the elevator ont to or throughthe side of the apparatus. A part of this chute adjacent to the elevatoracts as a trap or valve, and is adapted to be raised, thus forming apassage through to the bin below, its position when up being shown indotted lines. A valve, 5, is located in the spout, through which thegrain passes to be elevated after having been directed to the bin andweighed. This operation is as follows: The grain is rst elevated fromthe car, and, by opening the trap or valve in chute C2, the said grainor material is directed to the bin below,where it is weighed and againelevated, 6o the said valve being closed. It is thus directed by thechute to the receiving car or vessel.

Having thus described my invention, what I claim is- Y 1. In a car forthe transfer of grain,wei ghi ng mechanism, in combination with averticallyadjustable bin, substantially as described.

2. In a car for the transfer of grain, weighing mechanism, incombination with a bin and means foiuraising and tilting it,substantially 7o as described.A

3. In a car for the transfer, or transfer and weighing, of grain, thecombination ofthe bin with the hinged car-sections S, for permitting itto assume the proper position for discharge.

4. The combination of the bin O, rope l?, and pulley Q with the guidewayXV and chute T, substantially as described.

5. In a car for the transfer, or transfer and weighing, o f grain, thecombination of the ele- 8o vating device, the chute M, the adjustablebin O, and the discharge-chute T, substantially as described.

(i. In a transfer, or transfer and weighing, car, the combination oftheupper chute, M, a 8 5 series of elevating devices feeding along itslength,with an elevating-bin, substantially as described.

' 7. The combination` in a transfer-car, of the elevating device with atransfer bin provided with a valved spout at its lower end, and a valvedor movable trough or chute for conveying the grain from the hopper orelevating device to the car to be loaded, or to other vessel,substantially as herein described.

In testimony that I claim Athe foregoing as my own I affix my signaturein presence of two witnesses.
